- Australia has practised road stabilisation for well over 50 years and this extensive experience has
resulted in considerable innovation in the design and construction of plant-mix and insitu processes
with various binders. Binder suppliers, contractors and road authorities have continued to develop
the process to ensure the completed pavement meets the design expectations and that there is a
sufficient tolerance in the specification to allow for the variable pavement materials expected in the
- This paper covers the following topics:
- Binders currently being used by road authorities
- Development of laboratory characterisation of the stabilised material
- Design models to establish layer thickness and traffic life
- Specifications to ensure best results
- New construction practices and issues
- Monitoring performance of existing pavements
- How the industry is working together to solve problems
- Road stabilisation has been practiced in Australia for so long that it is sometimes forgotten as one of the most successful recycling construction processes in Australia (see Figure 1). Many of these exciting developments and milestones are outlined on an oral history CD recently released by the Roads & Traffic Authority and titled Pavement Recycling and Stabilisation, (RTA, 2004). Told by local experts closely involved with stabilisation practices, this oral history provides a great opportunity to hear about past developments and the early days of road stabilisation.

- Professional Reinforcement Solutions is a reliable and dependable solution in building paved roads, unpaved roads, gravity retaining walls, soil reinforcement and green walls and so on. They have long time of experience in this kind road building http://www.prs-med.com/sustainability/recycled-materials …">Recycled Materials Services projects for near about 15 years.
- Cellular Confinement Systems is shortly known as CCS and also called geocells have been using in construction for the purpose of preventing soil erosion and or soil stabilization and other purpose such as steep slopes, channel protection as well as structural reinforcement for supporting load on earth retention. This technique is used for confinement systems are built with ultrasonically welded high-density polyethylene often known as HDPE which enlarged on site to and from a structure designed like a honeycomb, sometimes these honeycomb structure are filled with soil or rock material.
